This article presents the influence of moisture and temperature on the compressive properties of T-300/epoxy, thermosetting and APC-2, thermoplastic com posites. All the specimens were designed using quasi-isotropic configuration of [+45°/ 90°/-45°/0°] s. A temperature range of 23°C to 100°C was considered for both the dry specimens as well as those exposed to distilled water for a period of 90 days. The effect of specimen geometry on the moisture absorption rate is also reported.
